A block on a level surface is attached to one end of a spring, as shown in the figure. The other end of the spring is attached to a wall. There is friction between the block and the surface. A person displaces the block from its equilibrium position and releases it.

The spring constant is 20 N/m. During a certain time interval within an oscillation, the spring moves 0.2 m from its maximum expansion displacement to its equilibrium (central) position. The force of friction is 1.5 N. How much kinetic energy is transferred from the potential energy of the spring to the block over this time interval?

0.4 J

0.7 J

0.8 J

0.1 J

A pendulum is transported from sea-level, where the acceleration due to gravity g is 9.80 m/s2, to the top of a mountain. At this location, the period of the pendulum is increased by 3.00%. What is the value of g on the mountain? Use 3 sig figs to solve and round the

final answer to 2 sig figs.

9.0 m/s2

9.2 m/s2

9.4 m/s2

9.6 m/s2

9.8 m/s2
